BLL2453

16V, 3A, 500KHz COT Synchronous Step-Down DC/DC Converter

DESCRIPTION

FEATURES

The BLL2453 is a fully integrated synchronous

rectified step-down converter that provides wide

4.2V to 16V input voltage range and 3A continuous

load current capability. The BLL2453 can achieve

high efficiency and reduce power loss at light load.

In shutdown mode, the maximum supply current

is about 3μA.

•

Wide input voltage range: 4.2V to 16V

3A output current

0.8V reference voltage

Low R_DS(ON)integrated power MOSFET (80/50mΩ)

3μA(Max) shutdown current

Integrated internal compensation

High efficiency at light load

Internal 1ms soft-start

Cycle-by-cycle current limit

The BLL2453 protection function includes cycle-

by-cycle current limit, UVLO and thermal

shutdown. Besides, internal soft-start prevents

inrush current at fast power-on. This device uses

Constant On-Time (COT) control mode which

provides fast load transient response. Internal

loop compensation function reduces the external

compensator components and simplifies the

design process.

Over-temperature protection with auto recovery

Under voltage lockout (UVLO)

Hiccup short circuit protection

Available in tiny SOT563 and SOT23-6 packages

RoHS compliant

APPLICATIONS

The BLL2453 requires a minimum number of

readily available standard external components

and is available in tiny SOT563 and SOT23-6

packages.
